1) Collect like terms.
2) Simplify 
to 
.
3) Expand by distributing terms.
4) Collect like terms.
5) Simplify.
Therefore, the answer is x + 39 and there is only one solution possible.
Answer:
750
Step-by-step explanation:
You would divide 30 by 4 to get 1% then multiply by 100 to get the total amouny of readers
Let the units of the problem be miles and hours. The first plane's distance from point p can be described by
... x = 150 -450t
The second plane's distance from point p can be described by
... y = 200 -450t
Since their flight paths are at right angles, the Pythagorean theorem can be used to describe the distance between them (s).
... s² = x² + y²
... s² = (150 -450t)² + (200 -450t)² = 22500 -135000t +202500t² +40000 -180000t +202500t²
... s² = 40500t² -315000t +62500 = 2500(162t² -126t +25)
... s = 50√(162t² -126t +25)
2.83 x 305 ( of is always multiplication )
False
true
because 7 x 4 = 28 and 9 x 4 = 36 but in the first problem you can multiply any numbers.
